VELOCIPEDE.

SPECIFICATION forming part of Letters Patent No. 447,478, dated March 3, 1891.

Application filed November 12, 1890. Serial No. 371,165. (No model.)

To all whom it may concern:

Be it known that I, JosEPH SCHINDLER, a subject of the Emperor of Austria-Hungary, residing at Uittwa, No. 7, near Carlsbad, in Bohemia, Austria-Hungary, have invented certain new and useful Improvements in Velocipedes, of which the following is a specification.

This invention relates to a velocipede of improved construction, and more particularly to the mechanism for propelling the same.

The invention consists in the various features of improvement more fully pointed out in the claims.

In the accompanying drawings, Figure l is a side elevation of a bicycle provided with my improvement. Fig. 2 is a top view thereof with backbone and main frame removed. Fig. 3 afront view, and Fig. earearview of the driving-wheel; Fig. 5 a front view, and Fig. 6 a side view, of the pedal; Fig. 7, a vertical central section through the frictionclutch, and Fig. 8 a face view thereof. Figs. 5 to 8 are drawn on a larger scale than the other figures.

The letter A represents the shaft of the driving-Wheel A, such shaft being loosely surrounded by a pair of chain-wheels 13, connected to boxes 0, that also surround the shaft. lVithin boxes Othere are keyed to the shaft A the sockets D. In the sockets two cylindrical rods E' are secured, made in one piece with segments F, having a rounded working-edge. From the sockets D there project the arms H, to which are attached the springs G, theother ends of which are attached to the segments F. The springs G continually press the segments against the cylindrical inner face of boxes 0. As the chain-Wheels B are revolved forward, the boxes 0 take the segments F along to revolve the shaft A. If, however, the chain-wheels and boxes revolve backward, the latter glide over the segments ,without revolving them.

' As the right and left pedals are alternately worked, one box will thus always turn the shaft forward, so that acontinuous motion is imparted to the same. The chain, rope, or strap J passes from one chain-wheel around a front Wheel K, and thence around the other chain-wheel. It may be provided with a spring or elastic section U. Thetwo ends of the chain J are connected to the rear ends of two levers L, pivoted to levers N, that are in turn pivoteted to a fixed frame P by bolt 0. To the levers N there are furthermore pivoted a pair of rods Q, the forward ends of which are provided with teeth to constitute racks, Fig. 5. These racks pass through the eyes of sleeves R, that are mounted upon the shafts of the pedals M. These shafts are secured to the forward ends of the levers L. To the sleeves R are pivoted the pawl S, thrown into engagement with racks Q by springs P. hen the pawl is tilted against action of spring T, it becomes disengaged from its rack and thus the levers L can be turned and the pedals can be adjusted farther up or down. As soon as the proper adjustment has been made the pawl S is released to re-engage the rack and lock the pedals in position.

The improvement above described may be applied to velocipedes having two, three, or more wheels.

lVhat I claim is 1. The combination of chain-wheels K B and chain J with a pair of levers L, secured to the chain, pivot-ed levers N, on which levers L turn, and with pedals M on levers L, and racks Q, engaging the pedals, substantially as specified.

2. The combination of levers N with levers L and racks Q, pivoted thereto, chain J and pedals M, connected to levers L, sockets R, em bracing racks Q, pawls S for engaging such racks, and with chain-wheels 13, substantially as specified.

3. The combination of levers N with levers L and racks Q, pivoted thereto, chains J and pedals M, connected to levers L, chain-wheels B, boxes O, and segments F, operated by the chain, sockets R, embracing racks Q, and with pawls S for engaging such racks, substantially as specified.

In testimony whereof I hereunto sign my name, in the presence of two subscribing witnesses, this 24th day of October, 1890.
